Subject: powercap/intel_rapl: Fix domain detection
References: bsc#1178325
Patch-Mainline: v5.10-rc1
Git-commit: 7a57e9f112adebc9e5dc787c2a59dbc06ae5060d


As only the low 32 bits of the RAPL_DOMAIN_REG_STATUS register
represents the energy counter, and the high 32 bits are reserved,
detect the existence of a RAPL domain by checking the low 32 bits only.
